Development of a multimedia enhanced web prototype for technical learning instrument

Abstract

Inconveniences in apparatus preparation, increased number of students and time
constraints had caused the development of alternative learning instrument. Thus, a
research on development and evaluation of multimedia enhanced web site as a learning
instrument for metallogaphy subject was conducted. A website namely Visual
Metallography (VM) was designed and enhanced with multimedia as the information
transmission medium. Video clips were used to elaborate the specimen preparation
process in laboratory whereas; animation was included to enhance the interactive
circumstance. VMwas evaluated using questionnaire with a group of respondent.
Reliability level of instrument used was determined through a pilot test. Cronbach's alpha
for section 2, 3 and 4 were 0.942, 0.839 and 0.813 respectively. The research sample
comprised 50 engineering students of KUiTTHO enrolling for Metallography subject.
Research findings were analysed descriptively using SPSS 11.0 software. Referring to the
analysed data, 55 items were highly rated except for item 23, which rated at medium
level. In conclusion, the interface (GUI) design, multimedia provided and learning style
presented in VMweb were fulfilling the users' needs. VMis indeed suitable as a
multimedia-enhanced web based learning instrument purposely for lecturers and students
